Justice Clarence Thomas filed a 91-page dissent this week after the Supreme Court struck down President Trump’s executive order restricting birthright citizenship, warning that the majority’s reading of the 14th Amendment cheapens the meaning of American citizenship and will not hold up over time.
The Court’s decision, which invalidated the executive order Trump signed on his first day in office, drew a sharp constitutional objection from the longest-serving conservative currently on the bench. Thomas argued the majority got its history wrong, and that the consequences will outlast the current political moment.
The ruling marks one of the most significant constitutional rebukes of the Trump administration to date. But Thomas’s dissent lays down a detailed originalist counter-argument that conservative legal thinkers will study for years. At its core is a question the Court’s majority chose to answer one way and Thomas answered another: what did the framers of the 14th Amendment actually mean by “subject to the jurisdiction thereof”?
A 91-page rebuttal the Court didn’t hear aloud
Thomas did not read his dissent from the bench, an unusual choice for a justice lodging so extensive an objection. But the written opinion itself left little doubt about the depth of his disagreement. As The Hill reported, Thomas accused the majority of rewriting the history of the Citizenship Clause to reach a politically convenient result.
“The Court today takes the extraordinary step of holding facially unconstitutional the President’s Order excluding from citizenship the children of foreign temporary visitors and illegal aliens.”
That executive order, signed on Inauguration Day, sought to deny automatic citizenship to children born on U.S. soil to parents who were either in the country illegally or present only on temporary visas. The Supreme Court found it unconstitutional. Thomas said the order was “consistent with the original public meaning” of the Citizenship Clause.
His argument turned on the word “domicile.” Thomas contended that the Citizenship Clause, as understood at the time of ratification, applied only to people domiciled in the United States, not to the children of visitors passing through or residing here without legal authorization.
“The Citizenship Clause was consistently interpreted not to apply to the children of foreign temporary visitors, who were by definition not domiciled in the United States.”
He went further, arguing that the federal government itself, for decades after the 14th Amendment was ratified, denied citizenship claims from children born on U.S. soil but not domiciled here, regardless of which party held the White House.
The majority’s reasoning, and where Thomas broke from it
The majority opinion, authored by Chief Justice John Roberts, held that the 14th Amendment plainly guarantees citizenship to all persons born on U.S. soil. The Washington Times reported that Roberts wrote for a 6-3 majority, with Justice Brett Kavanaugh providing the decisive sixth vote, though on narrower grounds. Kavanaugh concluded the executive order violated federal statutory law passed by Congress in 1952, rather than the Constitution itself.
Roberts framed the ruling in sweeping terms. “Citizenship, then and now, was the right to have rights, to freely participate in our political community,” he wrote. “We keep that promise today.”
Thomas rejected that framing root and branch. He argued the majority erred in concluding that “subject to the jurisdiction thereof” should be understood through the lens of a “feudal” principle of allegiance rooted in English common law, a principle he said was codified as “not subject to any foreign power” in the Civil Rights Act. In Thomas’s view, that phrase excluded the children of foreign nationals who had no permanent ties to the country.
He also took aim at the majority’s reliance on the landmark Wong Kim Ark ruling, contending that precedent should not extend to cover children of foreign temporary visitors. The long-anticipated ruling had been closely watched by legal scholars on both sides of the debate.
Thomas’s historical case
The dissent leaned heavily on original public meaning, the interpretive method most associated with the late Justice Antonin Scalia and now championed by the Court’s originalist wing. Thomas cited historical figures from the Reconstruction era, including Representative Bingham and Senator Trumbull, as well as Justice Harlan, all of whom he argued understood the Citizenship Clause as limited to those with permanent ties to the United States.
The Washington Examiner reported that Thomas accused the majority of relying on “alternative history” to reach its conclusion. His dissent framed the 14th Amendment as originally designed to secure equal rights for freed Black Americans, not to create an automatic pathway to citizenship for anyone born within U.S. borders regardless of their parents’ legal status or intent to remain.
“In doing so, the Court adds to the sad history of the Fourteenth Amendment, which was designed and understood to secure equal rights for the freed blacks but has instead been repurposed for political projects that the Reconstruction Congress did not support.”
That line may prove the most debated passage of the dissent. Thomas is arguing that the amendment’s purpose has been stretched far beyond what its authors intended, a claim that cuts against more than a century of settled practice but aligns with a growing body of originalist scholarship.
Thomas was not alone in dissent. Newsmax reported that Justices Samuel Alito and Neil Gorsuch joined him, making the final vote 6-3.
What comes next
President Trump responded to the ruling by calling on Congress to act legislatively on birthright citizenship. But Roberts’s majority opinion, grounded in constitutional rather than statutory reasoning, appears to foreclose any legislative fix short of a constitutional amendment, a point the Washington Times noted in its coverage. Trump himself had previously acknowledged the likelihood of losing the case at the high court.
The ruling does not end the broader political fight over immigration and citizenship. It does, however, settle, for now, that the executive branch cannot unilaterally redefine who qualifies as a citizen at birth. Thomas’s dissent ensures the originalist counter-argument is on the record in full, available for future litigants and future Courts to revisit.
Thomas’s willingness to stake out lonely ground is nothing new. He has repeatedly urged the Court to revisit precedents he considers wrongly decided, from voting rights to trucking licenses for illegal immigrants. His past rebukes of the Court for declining cases he believed deserved review follow the same pattern: a long-tenured justice who would rather be right than popular.
The 91-page dissent also lands during a term in which Thomas has been unusually active. He recently wrote for a near-unanimous bench in a property claims case involving Cuba, a reminder that his influence on the Court extends well beyond the cases where he finds himself outvoted.
The Court’s 8-1 ruling earlier this term striking down Colorado’s conversion therapy ban on First Amendment grounds showed that the current bench is willing to challenge government overreach in other contexts. But on birthright citizenship, the majority drew a firm constitutional line that even Kavanaugh, who broke with the majority’s reasoning while joining its result, was unwilling to cross.
The real question Thomas is asking
Strip away the legal citations and historical arguments, and Thomas’s dissent poses a question that millions of Americans have been asking for years: does citizenship mean anything if it is automatically conferred on anyone born within the nation’s borders, regardless of whether their parents had any lawful right to be here?
The majority says the Constitution answers that question clearly. Thomas says the majority is reading a different Constitution than the one the Reconstruction Congress wrote.
“I am not sure that today’s opinion will stand the test of time. The Citizenship Clause ‘added greatly to the dignity and glory of American citizenship.’ Today’s opinion devalues that citizenship.”
Whether or not future Courts revisit this ruling, Thomas has ensured the dissent is thorough enough to serve as a blueprint. Ninety-one pages is not a protest. It is an invitation to the next generation of justices to look again.
And if the history Thomas cites is even half as clear as he claims, the majority may one day wish it had looked harder the first time.
